Risto Kalervo Näätänen (born June 14, 1939 in Helsinki, Finland) is a psychological scientist, pioneer in the field of cognitive neuroscience, and known worldwide as the discoverer of the electrophysiological mismatch negativity. He has been a much-cited social scientist and one of the few individuals appointed permanent Academy Professor of the Academy of Finland. He retired in 2007 , retaining a title of Academy Professor emeritus of the Academy of Finland. Since 2007, he has been a professor at the University of Tartu.
He started to study psychology in the University of Helsinki in 1958, training in cognitive electrophysiology at the laboratory of Donald B. Lindsley at the University of California, Los Angeles (1965-1966). Under Lindsley’s supervision, he defended his doctoral dissertation about brain mechanisms of selective attention at the University of Helsinki in 1967. As early as that he started to influence the scientific world: in his thesis he refuted a then well-known experimental design and no works have ever been published using that design again.
In 1975, at an age of 36, having published 13 academic articles, he was appointed as a Professor of General Psychology at the University of Helsinki. In practice, he was at that department until 1999, but officially on leave from 1983, being salaried as an Academy Professor of The Academy of Finland. He is founder of the Cognitive Brain Research Unit (CBRU) at the University of Helsinki - a unit of which he was director from 1991-2006.
In 2007, he reached the retirement age of 68 . A retirement symposium was held in his honor in 2008. Since 2008, he has been a Professor of Cognitive Neuroscience at the University of Tartu, Estonia, Visiting Professor at the Centre of Functionally Integrative Neurosciences (CFIN) of the University of Århus, Denmark, retaining a tertiary affiliation at the University of Helsinki as of May 2014, having held the title of an Academy Professor emeritus of the Academy of Finland since retirement.
He has sat on editorial boards and reviewed for specialist journals (e.g., Brain Research, International Journal of Psychophysiology, Journal of Cognitive Neuroscience, NeuroReport). He has published articles from collaborations with thousands of researchers. As of June 2014, according to Google Scholar no collaborators are listed as co-authors and citations totalled 43758 (16541 since 2009) resulting in an h-index of 108 (60 since 2009), being amongst the 0.5% most-cited scientists still alive, the most-cited scientist in Finnish and Estonian history.
His life work revolved around the mismatch negativity (MMN) first revealed in collaboration with Anthony W.K. Gaillard, and Sirkka Mäntysalo in reinterpretion of the prior findings of an early selective attention effect - discovered by Steven Hillyard - as a consequence of experiments that were carried out in the Institute for Perception TNO, Soesterberg, The Netherlands, in the summer of 1975, by Sirkka Mäntysalo. MMN has been established as a scalp-negative component of the event-related potential or ERPs, as derived from recordings made electroencephalographically via electrodes attached to the scalp. MMN was shown to be elicited by deviant stimuli interspersed amongst a series of standards.
MMN has influenced theories of language perception, together with studies of cognitive development and musical intelligence. Risto Näätänen has been most interested in the clinical scope: abnormalities of MMN have been associated with alcoholism, psychosis in schizophrenia, Alzheimer's disease, Parkinson's disease, and dyslexia. Facets of MMN have been associated with the prediction of waking in comatose individuals - as has been hailed as a breakthrough - yet MMN has remained a research tool and has not met criteria to determine clinical decisions about the continuation of life support.
Risto Näätänen's major societal impact was to influence Finnish traffic politics, his studies of traffic behavior - conducted during the presidency of Kekkonen - leading to the establishment of speed limits on Finnish roads. Reaching the age of 74 in 2013, he expressed hopes that MMN would be implemented in education.
